| Pin | Signal / Name | Typ | Alternative Funktionen |
|---|---|---|---|
| 1 | OUT B | Digital | Comparator B Output (Open-Collector — requires pull-up resistor; LOW when INB+ < INB-) |
| 2 | OUT A | Digital | Comparator A Output (Open-Collector — requires pull-up resistor; LOW when INA+ < INA-) |
| 3 | V+ | Power | Positive Supply Voltage (+2V to +36V single-supply, or ±1V to ±18V dual-supply) |
| 4 | INA- | Analog | Inverting Input (-), Comparator A — output goes LOW when INA- > INA+ |
| 5 | INA+ | Analog | Non-Inverting Input (+), Comparator A — output goes LOW when INA- > INA+ |
| 6 | INB- | Analog | Inverting Input (-), Comparator B |
| 7 | INB+ | Analog | Non-Inverting Input (+), Comparator B |
| 8 | INC- | Analog | Inverting Input (-), Comparator C |
| 9 | INC+ | Analog | Non-Inverting Input (+), Comparator C |
| 10 | IND- | Analog | Inverting Input (-), Comparator D |
| 11 | IND+ | Analog | Non-Inverting Input (+), Comparator D |
| 12 | V- | Ground | Negative Supply / Ground (0V for single-supply; negative rail for bipolar supply) |
| 13 | OUT C | Digital | Comparator C Output (Open-Collector — requires pull-up resistor; LOW when INC+ < INC-) |
| 14 | OUT D | Digital | Comparator D Output (Open-Collector — requires pull-up resistor; LOW when IND+ < IND-) |
